Abstract

The utility model provides a coal-saving gasification furnace, comprising a furnace shell, a furnace core and an aqueous layer for heat insulation. The upper part of the furnace shell is provided with a feed port and a gas outlet, the lower part of the furnace shell is provided with a slag hole, an ash hole and an air feeding hole, and the aqueous layer for heat insulation provided between the furnace shell and the furnace core is provided with an inlet and an outlet. The utility model is characterized in that the air feeding hole on the furnace shell is connected with the air feeding chamber in the furnace shell, the air feeding chamber is connected with each air feeding pipe distributed on the furnace core, the gas outlet on the furnace core is positioned on the burning gasification layer and is connected with the gas outlet on the furnace shell by the gas passage arranged on the aqueous layer for heat insulation. The utility model not only solves the technical problem of homogeneous air feeding and complete burning, but also overcomes the insufficiency that the gas is taken only on the dry distillation layer in prior art, impossible of guaranteeing the gas purity and reducing the tar content of the coal. The coal-saving gasification furnace not only makes the user convenient, but also improves the heat efficiency and the gas combustion value, additionally the aqueous layer for heat insulation can provides hot water or steam, so the synthetic effect of energy saving is conspicuous. The utility model is an ideal energy-saving coal-fired gasification furnace.

Description

The vapourizing furnace of economizing on coal

Technical field

The utility model relates to a kind of coal-fired gasification furnace, especially a kind of coal-fired gasification furnace with effect of coal saving.

Background technology

The coal-fired gasification furnace that uses adopts refractory materials to make lining mostly at present, not only causes furnace body temperature too high, scalds the people easily, but also limited heat energy is wasted, and at the bottom of the comprehensive utilization ratio, can't economize on coal.Existing coal-fired gasification furnace also exists coal gas and takes place slowly in addition, and coal tar is many, and the flue dust when banking up a fire is too big, easily causes problems such as environmental pollution, brings the consumption coal, uses many troubles and unfavorable such as inconvenience, coal tar pollution to the user.Therefore, be necessary prior art is improved.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of prior art, and providing a kind of can economize on coal, and the vapourizing furnace of economizing on coal of coal gas and hot water can be provided again simultaneously.

The utility model is realized by following technical proposal: comprise that its top is provided with opening for feed, gas exit, its underpart is provided with the furnace shell and the flue of slag notch, ash output hole, air feed mouth, be located at the heat insulation water layer which is provided with import and export between furnace shell and the flue, it is characterized in that the air supplying chamber in blast inlet and the furnace shell on the furnace shell is communicated with, air supplying chamber is communicated with each air feed pipe on being distributed in flue, gas exit on the flue is positioned at the combustion gasification layer, and the gas flue by placing heat insulation water layer is communicated with gas exit on the furnace shell.

Blast inlet on the described furnace shell links to each other with the blower fan of outside by pipeline, so that provide the uniform combustion-supporting air of using by the blast inlet on pipeline, the furnace shell, the air supplying chamber in the furnace shell, each the air feed pipe that is distributed on the flue in flue, thereby improves efficiency of combustion.

Gas exit on the described furnace shell links to each other with furnace shell gas filter drain cock outward, this strainer links to each other with the gas chamber which is provided with the coal tar relief outlet, gas chamber links to each other with user's air-supply duct by pipeline, valve, the coal gas that will produce so that will burn enters gas chamber after filtering through filter, gives the user by main force's air again and uses.

Described strainer is by the casing which is provided with lid and be movably arranged on the intravital filtering net of case and constitute, so that after opening case lid as required, takes out filtering net and cleans or change, and guarantees the filter effect of coal gas.

The utility model compared with prior art has following advantage and effect: according to such scheme, it is even both to have solved air feed, the technical problem completely of burning, overcome prior art again and only got coal gas at the destructive distillation layer, be difficult to guarantee coal gas purity, can't reduce deficiencies such as coal tar oil mass, by filtration, purification to coal gas, significantly reduced the pollution problem that coal tar causes to the user, both made things convenient for the user, and improved thermo-efficiency and coal gas combustion value again simultaneously, heat insulation in addition water layer can provide required hot water or steam to the user, effectively reduce coal-fired consumption, the synthesis energy saving effect is remarkable, therefore, is the energy-saving coal-fired gasification furnace of an ideal.
